2 Claims; A((31. 268-125) The object of my invention is to provide a simple and effective window operating device adaptable for use wherever vacuum or air pressure is available for practical use.

g More particularly, it is my purpose to provide which:

a window operating mechanism particularly` adapted for use in raising and lowering the' windows of automobiles.

In this connection, it is my purpose to provide anapparatus which may be connected with some vacuum creating mechanism of the car and used for raising and lowering windows.

Another particular object of the invention is to provide means for operating the apparatus on a swinging door.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my window operating device, whereby the objects contemplated are attained, as hereinafter more fullyrset forth, pointed out in my claims, and

illustrated in the accompanying drawings, in

My invention is illustrated herein as applied to an automobile.

In the drawings, I have shown in Figure 1 a perspective view of a part of the interior oi an automobile 10 having the vertically sliding win-.-

dows 11 and 12. The windows 12 are in the doors of the automobile.

My invention involves apparatus for operating these windows by vacuum or pressure. It is i1- lustrated here as operating from the engine as a vacuum creating means.

In Figure 2, I have shown the inside oi the automobile door 13, having the vertically sliding pane of glass i4. 'I'his .glass has connected with its lower edge. a guide element 15, having the horizontally elongated slot 16. There is a substantially standard structure provided for operating such awindow. It consists oi' .a suitably `mounted toothed pinion 17, journaled on thel plate 24 of the door and operated by means of a. shaft 18, on which is a handle 20 inside the door. A sleeve 21 non--slidably but rotatably mounted supports the shaft 18, which is angular in outline. The shaft v18 has threaded on its outer end the head 22. This shaft is slidable lengthwise. This shaft is slidable for the purpose of throw-1 ing the pinion 17 into and out of gear with the toothed sector 23. This means for throwing the pinion in and out of gear is peculiar to my structure.

The toothed sector 23 is journaled on the supporting plate 24 by means ofy a shaft 25. I provide a spring washer 26 for holding the sector 23 in any position oi' its movement. The sector 23 has a projecting arm 27, which i'n the form of the device shown in Figure 2 has an elongated slot 28, pivoted as at 29 to a plunger stem 30.

The stem 39 is -connected with a plunger 31 in a ilxed cylinder 32.

There is provided the spring 33 connected with the. arm 27 and with the frame o! the door for balancing the window.

The sector 23 has another arm 3 4 from which a `pin 35 projects into the elongated slot 16.-

Thus 'by operating the sector 23, the window may be raised or lowered. By pushing the shaft 18 inwardly until the pinion 17 meshes with the sector 23, the window may be raised or lowered by hand.

I will now describe the means for operating the'plunger for operating the window by power.

Power operating mechanism I vThe power operating mechanism includes the arm 27, thepllmger 31, and the means for connecting them together with the cylinder 32 and and has a stem 36 projecting inwardly and carrying an operating handle 37 (see Figures 1 and 2).

'Ihe detailsof the valve structure are illustrated in Figures 5, 6 and 7.

The valve casing 38 has a passage 39 connected with the vacuum tube 40and the spaced passages 41 and 42 connected with the tubes 43 and 44. The tube 43 communicates with the interior of the cylinder 32 at one end thereof through the passage 45, and the tube 44 communicates with the interior of the cylinder at its 'other end through the passage 46.

The tube 40 connects with some vacuum creating means.

It will be seen that the spring 33 normally tends to hold the window up even if there should be some leakage in the cylinder.

If it is desired then to lower the window, the operator grasps the handle 37 'and moves it to position where the passage 47 in the valve proper 48 registers with the passage 39 and with the passage 41. This action connects the left-hand end of the cylinder 32 as shown in Figure 2 with the source of vacuum.

The casing 38 has a passage 49 open to atmosphere and when the valve 48-is in the last-mentioned position, the air coming in through the passage 49 can pass through the passage 42 and the tube 44 and the passage 46 to the right-hand end of the cylinder 32. The air pressure forces the piston 31 toward the left, for thus lowering the window 14.

The valve can be readily manipulated for lowering the window any degree desired. l If the window is lowered to an intermediate position, it can be held'there by turning the valve 48 to its neutral position shown in Figure 6. Thereupon the connection with the source of vacuum is shut oil', the casing 38 has'an opening 50A to atmosphere, and when the valve it thus turned to its neutral position, both sides of the plunger 31 are subject to equal atmospheric pressure.

If then it is desired to raise the window, the valve is turned to position where its passage 4'?r registers with the passages 39 and 42 for connecting the right-hand end of the cylinder with the vacuum creating means. Thereupon air enters the left-hand end of the cylinder and forces the plunger or piston to the right for raising the window.

IZ the window towhich the yapparatus is con" Hinge line connection Referring to Figures 2 and 4, it will be seen that there is mounted in the frame of the door 13, a pipe or the like 51, to which the tube 40 is connected; The pipe 51.has an enlarged portion 51a terminating at the edge oi.' the door in a peripheral ilange 52 countersunk in the doorframe. -Screwed into the enlarged portion is a lcylinder-like member 53vhaving the valve oper ating stem 54 projecting beyond the edge of the door. The member 53 has a number-of air passages 55.

In the frame oi the car is mounted a pipe or the like 56 having an enlarged portion 51 'terrnif4 nating at the edge of the frame adjacent to the door in an enlarged cup-like member 58. The tube 56 connectsv with a pipe 59 leading to any suitable source ot vacuum. 111e enlargedv porl tion 57 of the tube 56 has near the cup-like portion 58 an inwardly projecting threaded ilange 60 into which is screwed a valve cage'61, having the seat 62 for cooperation with aball check valve 63 held normally seated by a spring 64. For cooperating with the cup-like member 58. I pro-v vide a rubber gasket or the like 65, having the sleeve-like portion 66 projecting into the enlarged part 51a of the tube 51 as shown in Figure 4.

The gasket and its sleeve 66 have a passage 67 extending through them for the flow oi.' air.

In Figure 4, the parts are shown with the door slightly open, whereupon the spring 64 will cause the ball check valve 63 to be snugly seated. How- 90 ever, vwhen the door is closed, the member 54 pushes the ball 63 oli its seat, and thus leaves the tube 59 in free communication with the tube 40.,

The structure shown provides a tight `ioint when the valve is unseated.

Modified form,

In Figures 8 and 9, I have shown a form of. my invention involving certain modifications.

The valve B is shown mounted on the frame 160 of the car adjacent the hingeline Joint. 'Ihe construction thus employed is further illustrated in Figures 10 and 11.

In the construction just mentioned, there is provided the cylinder 32a, similar to the4 cylinder 32, but instead of .mounting it rigidly onlthe inside of the door, I pivot it at one end as at 68. The plunger stem 30a is then plvoted to an arm 27a on the sector 23, which is similar to the arm 27, except that it does not have the elongated 11o slot 28. The piston 32a in this form of the device rocks from its position for instance shown by full lines in Figure 9 to its position shown in dotted lines in that ligure.

'I'he piston 32a has passages at Iits ends through its'wall communicating with tubes 69 and '10', which in turn are connected with-pipes 'il and '72. These pipes have at their ends farthest from the cylinder 32a portions 71a and 72a turned at right angles and extended through the door and projected into the block 'i3 mounted on the inside or the door, extending to the hinge line thereof.

The ends of thetube portions 71a and "12a communicate with es 'I4 and 'i5 extending 125 through'the block 73 ,and having at their ends f farthest' from the tube members the gaskets 65 similar to that already described. y

'Ihe valve B is similar in construction to the valve A with exceptions that will be mentioned. 13o Its casing 38a has-in its wall a :.f e 39a simi lar to the passage 39 and connected with a tube '76, which in turn is connected with soms vacuum creating means. The casing 38a has a short extension 77 through which extend 'passages 41a 135 and 42a. The extension 77 is formed at the outer ends of the passages 41a and 42a with seats 78 for the gaskets 65. Y

The casing 38a has the air -::f-: 49a and 50a similar to-thees 49 and 50 aireadylm described.

'I'he valve 48a differs somewhat in shape from the valve 48 as shown best in Figure 11. The stem 36a of the valve 48a projects through the casing 38a and has an arm 80, the movement o! 145 which is limited by suitable stops 81. Either type of cylinder may be used with either type o! valve.

I have provided means for operating the arm 80 from the steering post near the steering wheel 150 In Figure 8, I have shown a steering post 82 on which is a steeringwheel 83. A rod 84 is journaled in brackets 85 and 86 and has the handle 88 near the steering post and the angular extending arm 87 at its lower end.

Suitably mounted is a iiexible stiiI wire tube 89 of well-known construction. Extending through this is a wire 90, which isv connected to the arm and to the arm 87, so that by manipulating the handle 88, the wire 90 may be moved lengthwise for operating the arm 80.

In Figure 8, I4 have also shown a reserve vacuum tank 91, mounted forwardly of the dash and connected by a tube 92 with the vacuum creating means. Seated in the bottom of the tank 91 (see Figures 8 and 12) and communicating with the interior of the tank is a valve cage 93 in which is a spring-pressed ball check valve 94. The valve cage connects with the tube 92.

It will thus be se'en that I have provided a I simple and eiective apparatus for operating windows, which is particularly adapted for use in operating windows in hinged doors.

In Figure 1, I have shown-an apparatus mounted on the inside of a door with the. valve operating handle .on the door. In the particular type of device shown here, the cylinder is ilxed and play is allowed between the plunger stem and the operating arm for the sector 23. Inv this form of device, there is shown means illustrated in Figures 2 and 4 for making a proper joint provided with a check valve at the hinge line of the door.

I have shown as particularly illustrated in Figure 3 means for operating the window by means of a handle, which means include thepivotal pinion 17 that can be thrown out of gear when desired.

In Figure 9 is illustrated a slightly diierent form of the invention in which the cylinder has a slight pivotal movement.

I have also shown in Figures 8 and 9 a means for operating the valve from the steering column.

In Figures 8 and 12, I have shown an auxiliary vacuum tank, which may be employed -in connection with my` invention.

With a device of this kind, the operator simply turns the valve to the proper position and the window is raised or lowered. It may be' stopped in any position of its adjustment and there held.

I preferably use the means for manually controlling the window with all forms of my device.

vThus the windowv can be raised or lowered by hand when the engine is not running.

It will be seen that by very slight modifications, it would be possible to use compressed air or steam instead of vacuum for operating an apparatus of this kind. e

Changes may be made in the details of the arrangement of the construction of the parts of my window controlling device, and it is my intention to cover by my claims any such changes inthe use of any `materials or arrangement of parts, which may be within the reasonable scope of my invention. y I claim as my invention:
